Q. 105.0( 2 Votes )

Solve the following systems of equations graphically:

Answer :

For the equation 2x + 3y + 5 = 0,

When x = -1 , y =- 1
When x = 5 , y =- 5
Table is :


Plot the points A(-1,-1) B(-5,5) on the graph

For the equation 3x – 2y – 12 = 0 ,

When x = 0, y = -6
When x = 2 , y = -3
Table is :


Plot the points C(0,-6) D(2,-3) on the graph


Since the two lines meet at the point (2,-3)
Therefore, x = 2 and y = -3
